Answer 1

1. Alkali metals: Group 1 elements are referred to as Alkali metals. These elements are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr).
2. Second-period elements: The second period of the periodic table has Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), and Neon (Ne).
3. Hence, the alkali metal in the second period is Lithium (Li).
